I wrote an article for Baeldung on the keyboard shortcuts that we need to edit, build, and run Java applications in JetBrains' Java IDE, IntelliJ IDEA. Keyboard shortcuts save us time because we can keep our hands on the keyboard and get things done faster.
I wrote an article for Baeldung on various ways of reducing the size of JSON in our Java applications. Java applications often use JSON as a common format for sending and receiving data. Moreover, it's used as a serialization protocol for storing data. With smaller JSON data sizes, our applications become cheaper and faster.
